Sutherland Springs is a small South Texas town, about 45 minutes southeast of San Antonio. On Sunday morning, some of its residents went to services at the First Baptist Church downtown.

Then a gunman shattered the calm of the morning. Devin Patrick Kelley, a 26-year-old from New Braunfels, a city 35 miles north, arrived dressed in black, wearing body armor and firing an assault-style rifle. He shot at the church building itself. And then he went inside and fired on the worshippers. He killed at least 26 people and wounded some 20 others.
